\(=\left(\dfrac{1}{6}\cdot6\right)^2+\dfrac{0.2^5\cdot0.3^5}{0.2^5\cdot0.2}\)

\(=1+\dfrac{0.3^5}{0.2}\)

\(=1+\dfrac{243}{20000}=\dfrac{20243}{20000}\)

\(\left(\dfrac{1}{6}\right)^2\times6^2+\left(0,6\right)^5\div\left(0,2\right)^6\)

\(=\dfrac{1}{36}\times36+\dfrac{243}{3125}\div\dfrac{1}{15625}\)

\(=1+1215\)

\(=1216\)

\(\left(\dfrac{1}{6}\right)^2\) . \(6^2\) + \(\dfrac{\left(0,6\right)^5}{\left(0,2\right)^6}\)

= \(\dfrac{1}{36}\) . 36 + 1215

= 1 + 1215

= 1216

bằng 1215

a) \(\dfrac{2^7.9^3}{6^5.8^2}=\dfrac{2^7.\left(3^2\right)^3}{\left(2.3\right)^5.\left(2^3\right)^2}=\dfrac{2^7.3^6}{2^5.3^5.2^6}=\dfrac{3}{2^4}=\dfrac{3}{16}\)

a) \(\dfrac{2^7.9^3}{6^5.8^2}=\dfrac{2^7.\left(3^2\right)^3}{\left(2.3\right)^5.\left(2^3\right)^2}=\dfrac{2^7.3^6}{2^5.3^5.2^6}=\dfrac{2^7.3^6}{2^{11}.3^5}=\dfrac{3}{2^4}=\dfrac{3}{16}\) 

b) \(\dfrac{\left(0,6\right)^5}{\left(0,2\right)^6}=\dfrac{\left(0,2.3\right)^5}{\left(0,2\right)^6}=\dfrac{\left(0,2\right)^5.3^5}{\left(0,2\right)^6}=\dfrac{3^5}{0,2}=1215\)

(0,6)⁵ : (0,2)⁶

= \(\left(\frac{3}{5}\right)^5:\left(\frac{1}{5}\right)^6\)

\(=\frac{3^5}{5^5}:\frac{1^6}{5^6}\)

\(=\frac{3^5}{5^5}.5^6=3^5.5=243.5=1215\)

(0,6)⁵ : (0,2)⁶ 

\(=\left(\frac{3}{5}\right)^5:\left(\frac{1}{5}\right)^6\)

\(=\frac{3^5}{5^5}:\frac{1^6}{5^6}\)

\(=\frac{3^5}{5^5}:\frac{1}{5^6}\)

\(=\frac{3^5}{5^5}.5^6=3^5.6=243.6=1458\)

Bạn gõ lại cho rõ đề được không?

\(\frac{\left(0,2.3\right)^5}{0,2^6}\)=\(\frac{0,2^5.3^5}{0,2^6}\)=\(\frac{3^5}{0,2}\)=\(\frac{243}{0,2}\)=1215

\(\frac{\left(0,6\right)^5}{\left(0,2\right)^6}=\frac{\left(\frac{3}{5}\right)^5}{\left(\frac{1}{5}\right)^6}=\frac{3^5}{5^5}:\frac{1^6}{5^6}=\frac{3^5}{5^5}.5^6=3^5.5=243.5=1215\)
